Trace element analyses of melt inclusions from Mount St. Helens 1980 eruption
Laser ablation (LA) ICP-MS analyses (presented in parts per million, ppm) of melt inclusions from the 1980 eruption of Mt. St. Helens (18th May-16th October). Detailed sample collection methods are given in Blundy et al. (2008). Blundy, J., Cashman, K.V. and Berlo, K. (2008) Evolving magma storage conditions beneath Mount St. Helens inferred from chemical variations in melt inclusions from the 1980-1986 and current (2004-2006) eruptions, in: Sherrod, D.R., Scott, W.E., Stauffer, P.H. (Eds.), A volcano rekindled: the renewed eruption of Mount St. Helens, 2004-2006, Reston, VA, pp. 755-790.

Trace element data was analysed by LA-ICPMS/MS at the Open University using a Photon Machines Analyte G2 193 nm excimer laser system coupled to an Agilent 8800 ICP-QQQ following the techniques described in Reekie et al. (2019). Melt inclusions were analysed at varying spot sizes depending on the diameter of the inclusion. The surface of melt inclusions were preablated (3 laser shots) prior to analysis. Backgrounds were measured for 30 seconds prior to each analysis, followed by 20 seconds of signal and 50 seconds of washout. NIST-SRM 612 was used for external calibration of trace element data.
